I went Biscuit this year and now I wonder why I resisted for so long
I don't seem to have any problems re: fletchings, I'm shooting 4" vanes and have shot each of my arrows 25+ times. I bought my rig at Cabela's (Fred Bear Buckmaster 4000) so I guess the guys there set it up right.
The big plus is that the rest is just so simple- no timing, moving parts, or arrows falling off the rest. As Ron Popeil says: "
Just set it, and forget it!"
The downside, some guys talk about the loss of speed. My bow is rated 310fps IBO, so unless my arrows start bouncing off deer I'm not going to think about it.
